    So i have a 2005 1500 Silverado and just of late it has started to burn oil, i figured it is burning oil becasue it isn't leaking any oil any where i have been trying to find a leak and have not been able to find one so at this point i believe it is burning it. The truck is straight piped ran with no mufflers it has edlebrock shortty headers, different underdrive pulley. If anyone has any input or info, or just anything to say that they think i should do let me know!! Thanks!

    burns oil

    I would look at the spark plugs for oil residue.

    A heavier oil may stop oil burning to some point. However you may notice a slight decrease in fuel economy.

    How many miles are on your truck? and what size engine? and how much oil are you burning, a quart every 1000 miles?
